Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to an integrated rapid purification reaction device for domestic sewage. Background Technology

[0002] Currently, the mainstream method for treating domestic sewage is to combine activated sludge oxygenation technology with MBR (membrane bioreactor) systems. These two technologies each play their respective roles in sewage treatment, and their synergistic effect significantly improves treatment efficiency and effluent quality, meeting the demand for "rapid purification".

[0003] Activated sludge oxygenation technology primarily functions to efficiently degrade organic pollutants and nitrogen. By injecting high concentrations of oxygen into the reactor, it maintains the high activity of aerobic microorganisms in the sludge, thereby accelerating the removal rate of COD (chemical oxygen demand), BOD (biochemical oxygen demand), and ammonia nitrogen in wastewater, providing a foundation for rapid purification.

[0004] The MBR system is responsible for efficient solid-liquid separation and water quality assurance. It replaces the traditional secondary sedimentation tank with microfiltration (MF) or ultrafiltration (UF) membranes to retain activated sludge and large molecular organic matter in the bioreactor, reducing the content of suspended solids in the effluent and enabling the treated water to meet high standards for discharge or reuse.

[0005] However, in actual use, the membrane fibers are prone to swaying and wear due to the water flow disturbance generated by aeration, which affects the stability and lifespan of the system. At the same time, the water flow disturbance can also carry activated sludge into the membrane fiber area, causing blockage and pollution, increasing the difficulty and cost of maintenance. Summary of the Invention

[0006] To address the problems mentioned in the background section, this invention provides an integrated rapid purification reaction device for domestic sewage.

[0007] The technical solution of the present invention is as follows: an integrated rapid purification reaction device for domestic sewage includes a protective box, which contains an equipment area and a treatment area. An aeration device is installed in the treatment area, and a support frame is installed above the aeration device. A series of inclined plates arranged in a straight line and in a circular array are fixedly connected to the support frame. The inclined plates slope downwards from the side closest to the support frame to the side furthest from the support frame. The circularly arrayed inclined plates are fixedly connected to each other. A filter module is installed inside the support frame, and a first guide frame is fixedly connected inside the support frame. The filter module is located within the first guide frame.

[0008] Preferably, the cross-section of the first guide frame gradually decreases from the top to the bottom.

[0009] Preferably, an electric rotating roller is provided on the lower side of the support frame, and a shielding member for shielding the lower side of the support frame is wrapped around the electric rotating roller. A movable frame is slidably connected to the lower side of the support frame, and an elastic member is provided between the movable frame and the support frame. The movable frame and the shielding member are fixedly connected to the side of the electric rotating roller that is not wrapped around it.

[0010] Preferably, a second guide frame is fixedly connected to the lower side of the first guide frame, and an electric push rod is fixedly connected to the first guide frame. A U-shaped frame is fixedly connected to the telescopic end of the electric push rod. The U-shaped frame is provided with a plurality of vertical sliding grooves. The second guide frame is rotatably connected to a swing plate distributed in a linear array. A connecting rod is fixedly connected to the swing plate. The plurality of vertical sliding grooves on the U-shaped frame correspond one-to-one with the connecting rods. The vertical sliding grooves on the U-shaped frame are used to press the adjacent connecting rods.

[0011] Preferably, the upper side of the second guide frame is provided with an inclined surface.

[0012] Preferably, the filter module includes a fixed frame, which is fixedly connected to the first guide frame. Several sets of connecting plates are fixedly connected within the fixed frame. Each set of connecting plates consists of two plates. The two connecting plates in the same set are jointly fixedly connected to two first guide frames. A first connecting post is fixedly connected between the two first guide frames. Each first guide frame has two centrally symmetrically distributed guide grooves. Several centrally symmetrical first sliding shells are slidably connected to each of the two first guide frames. The several first sliding shells slide along adjacent guide grooves. A second connecting post is fixedly connected between two vertically corresponding first sliding shells. A ring-shaped array of membrane fibers is fixedly connected and communicated between two vertically corresponding first sliding shells. The several first sliding shells on the upper side are jointly fixedly connected and communicated with a connecting tube.

[0013] Preferably, the guide groove consists of a spiral groove and a straight groove connected together.

[0014] Preferably, a connecting frame is rotatably connected between two adjacent first sliding shells, and a tension spring is provided between the first sliding shell near the first connecting post and the first connecting post.

[0015] Preferably, the connecting plate is provided with a rope winding component, which is used to pull the second connecting post away from the first connecting post.

[0016] Preferably, among the plurality of first sliding shells located on the upper side, the first sliding shells away from the first connecting post are slidably connected to a second sliding shell. A spring is provided between the second sliding shell and the adjacent first sliding shell. The second sliding shell is used to adjust the connection state between the adjacent first sliding shell and the adjacent connecting tube. The first guide frame located on the upper side is fixedly connected to two second guide frames. The second guide frame is provided with an inclined surface. The inclined surface of the second guide frame is used to press the adjacent second sliding shell.

[0017] Compared with the prior art, the beneficial effects of the present invention are: when purifying sewage, the present invention uses an inclined plate to shield the surging sewage, buffer the sewage, reduce the disturbance to the filter module, and form a semi-enclosed environment through the cooperation of the inclined plate and the first guide frame, weakening the dynamics of the activated sludge, so that the activated sludge will not move randomly after being placed in the inclined plate and the first guide frame, thereby reducing the amount of activated sludge entering the filter module area.

[0018] When the wastewater carrying sludge enters the support frame through the inclined plate, the sludge comes into contact with and is blocked by the first guide frame, allowing the sludge to fall freely along the outside of the first guide frame, thereby reducing the amount of activated sludge entering the location of the filter module.

[0019] During the wastewater treatment process, the activated sludge on the shielding components is cleaned, and the arrangement of several first sliding shells is changed from a straight arrangement to a spiral arrangement. By sealing the first sliding shells located outside the spiral groove in the guide channel, wastewater no longer enters the first sliding shells located outside the guide channel. This allows the membrane fibers located outside the guide channel to form a barrier, shielding the surrounding impurities and reducing the working pressure of the membrane fibers located inside the guide channel. This reduces the amount of wastewater entering while ensuring uninterrupted wastewater treatment. Attached Figure Description

Detailed Implementation

[0034] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings. Example 1

[0035] Integrated rapid purification reaction device for domestic sewage, such as Figures 1-6As shown, the device includes a protective box 1, which contains an equipment area 2 and a treatment area 3. The equipment area 2 contains a control terminal, a water pump, and other components. All electrical components mentioned in this device are electrically connected to the control terminal. The treatment area 3 contains an aeration device 4, which supplies oxygen to the treatment area 3 to provide a suitable environment for the activated sludge. The treatment area 3 also contains a support frame 5 located above the aeration device 4. The support frame 5 is fixed with inclined plates 6 arranged in a straight, circular array. The inclined plates 6 slope downwards from the side closest to the support frame 5 to the side furthest from the support frame 5. Inclined plates 6, arranged in a ring array, are fixedly connected. A filter module 7 is installed inside a support frame 5, and a first guide frame 8 is fixedly connected inside the support frame 5. The filter module 7 is located inside the first guide frame 8. The inclined plates 6 shield the surging sewage, buffer the sewage, and reduce disturbance to the filter module 7. In this embodiment, for ease of description, the aeration device 4 is consistent with the existing MBR system. Through the cooperation of the inclined plates 6 and the first guide frame 8, a semi-closed environment is formed, which weakens the dynamics of the activated sludge and prevents the activated sludge from moving randomly after being placed inside the inclined plates 6 and the first guide frame 8.

[0036] like Figures 5-7 As shown, the cross-section of the first guide frame 8 gradually decreases from the top to the bottom. When the sewage carrying sludge passes through the inclined plate 6 and enters the bearing frame 5, the first guide frame 8 guides the sludge, causing the activated sludge to fall.

[0037] like Figures 4-6 As shown, an electric roller 9 is provided on the lower side of the support frame 5. The electric roller 9 is wound with a blocking member 10 for blocking the lower side of the support frame 5. A movable frame 11 is slidably connected to the lower side of the support frame 5. An elastic member is provided between the movable frame 11 and the support frame 5. The movable frame 11 and the blocking member 10 are not fixedly connected to one side of the electric roller 9. When the electric roller 9 rolls up the blocking member 10, the blocking member 10 no longer blocks the lower side of the first guide frame 8. The elastic member can be a spring. When the blocking member 10 is not rolled up, the elastic member is not in a compressed state.

[0038] like Figures 6-8As shown, a second guide frame 12 is fixedly connected to the lower side of the first guide frame 8. An electric push rod 13 is fixedly connected to the first guide frame 8. A U-shaped frame 14 is fixedly connected to the telescopic end of the electric push rod 13. A linear array of swing plates 15 are rotatably connected to the second guide frame 12. A connecting rod 16 is fixedly connected to the swing plate 15. The U-shaped frame 14 is used to squeeze the connecting rod 16, causing the connecting rod 16 to drive the adjacent swing plate 15 to rotate. The U-shaped frame 14 is provided with several vertical sliding grooves, which correspond one-to-one with the connecting rod 16. When the U-shaped frame 14 moves to the right, the vertical sliding grooves on the U-shaped frame 14 squeeze the adjacent connecting rod 16, causing the connecting rod 16 to drive the adjacent swing plate 15 to rotate, thereby changing the tilt state of the swing plate 15. An inclined surface is provided on the upper side of the second guide frame 12 for guiding impurities or sludge.

[0039] To address the issues of membrane fiber oscillation and wear caused by aeration water flow disturbance and clogging / fouling caused by activated sludge entering the membrane fiber area, the following working principle is explained:

[0040] Working principle: When sewage needs to be treated, sewage is added to treatment zone 3. Aeration equipment 4 injects high-concentration oxygen into the sewage and activated sludge (activated sludge already exists in treatment zone 3 beforehand) to maintain the activity of aerobic microorganisms in the sludge and to perform initial treatment on the sewage through the activated sludge. After the above process continues for a specified time (time determined manually), the user then extracts the sewage from treatment zone 3 through filter module 7. During this process, inclined plate 6 shields the surging sewage, buffering it and reducing disturbance to filter module 7. When the sewage carrying sludge passes through inclined plate 6 and enters the bearing frame 5, the sludge contacts and is shielded by the first guide frame 8, causing the sludge to fall freely downwards along the outside of the first guide frame 8 until it falls onto the upper side of the shielding member 10. Through the above description, filter module 7 is placed in a semi-enclosed environment, thereby reducing the impact of sewage on filter module 7. The sewage then flows upwards from the lower side of the second guide frame 12 until it flows into the first guide frame 8 and is treated by filter module 7.

[0041] Before cleaning the activated sludge on the upper side of the shielding component 10, the control terminal extends the telescopic end of the electric push rod 13, causing the telescopic end of the electric push rod 13 to move the U-shaped frame 14 to the right. The vertical sliding groove on the U-shaped frame 14 presses against the adjacent connecting rod 16, causing the connecting rod 16 to rotate the adjacent swing plate 15, thereby changing the tilt state of the swing plate 15. After the swing plate 15 tilts, it achieves the effect of shielding the lower side of the first guide frame 8 (preparing for cleaning the shielding component 10), thus completing the preparatory action for cleaning the activated sludge on the upper side of the shielding component 10.

[0042] After completing the preparatory actions for cleaning the activated sludge on the upper side of the shielding component 10, the control terminal drives the shielding component 10 to rewind via the electric roller 9 (after the shielding component 10 is rewound, it no longer blocks the lower side of the support frame 5). During the rewinding process, the shielding component 10 drives the moving frame 11 to move synchronously to the left (the elastic element on the moving frame 11 stores power), and the activated sludge on the upper side of the shielding component 10 falls freely. After cleaning the activated sludge, the electric roller 9 releases the shielding component 10, and the elastic element on the moving frame 11 drives it to reset, so that the moving frame 11 drives the shielding component 10 to move and reset, thereby restoring the blocking of the lower side of the support frame 5. Then, the control terminal controls the telescopic end of the electric push rod 13 to drive the U-shaped frame 14 to move and reset to the left. The vertical sliding groove on the U-shaped frame 14 squeezes the adjacent connecting rod 16, so that the connecting rod 16 drives the adjacent swing plate 15 to rotate, so that all the swing plates 15 return to the vertical state and no longer block the lower side of the first guide frame 8.

[0043] Current methods for cleaning membrane fibers often involve interrupting the wastewater treatment process and disassembling the membrane fibers for cleaning. However, frequent disassembly and reassembly can cause physical damage to the membrane fibers, such as breakage or deformation, affecting filtration efficiency and service life. Furthermore, this cleaning method can lead to discontinuous operation of the treatment system, impacting overall treatment efficiency and stability. To address these issues, this invention is described below: Example 2

[0044] Based on Example 1, such as Figure 6 and Figures 9-12As shown, the filter module 7 includes a fixed frame 701, which is fixedly connected to the first guide frame 8. Several sets of connecting plates 702 are fixedly connected within the fixed frame 701, with two connecting plates in each set. In this device, there are two sets of connecting plates 702 on the same fixed frame 701. This number is only for describing this device and is not a limitation. In actual use, the user can adjust the number of connecting plates 702 according to the actual situation. Two connecting plates 702 in the same set are jointly fixedly connected to two first guide frames 703. A first connecting post 704 is fixedly connected between the two first guide frames 703. Each first guide frame 703 is provided with two centrally symmetrically distributed guide grooves 705. Both first guide frames 703 are slidably connected to centrally symmetrical... Several first sliding shells 706 slide along adjacent guide grooves 705. A second connecting post 707 is fixed between two corresponding first sliding shells 706. A ring array of membrane filaments 708 is fixed and connected between two corresponding first sliding shells 706. Several first sliding shells 706 on the upper side are fixed and connected to a connecting pipe 709. When sewage needs to be purified, the sewage passes through the membrane filaments 708 and enters the upper first sliding shell 706. The first sliding shell 706 guides the sewage to the connecting pipe 709 and discharges it through the connecting pipe 709. The sewage is purified by physical filtration. The guide groove 705 is composed of connected spiral grooves and straight grooves.

[0045] like Figure 10 and Figure 11 As shown, a connecting frame 710 is rotatably connected between two adjacent first sliding shells 706. A tension spring is provided between the first sliding shell 706 near the first connecting post 704 and the first connecting post 704 (this tension spring is in a stretched state when several adjacent first sliding shells 706 are arranged in a straight line). The connecting frame 710 is used to connect several first sliding shells 706 into a whole. The connecting plate 702 is provided with a rope winding member 711. The rope winding member 711 is used to pull the second connecting post 707 away from the first connecting post 704. The rope winding member 711 can be an existing underwater electric winch.

[0046] like Figures 10-13 As shown, among the several first sliding shells 706 located on the upper side, the first sliding shell 706 furthest from the first connecting post 704 is slidably connected to a second sliding shell 712. A spring is provided between the second sliding shell 712 and the adjacent first sliding shell 706. The second sliding shell 712 is used to adjust the connection state between the adjacent first sliding shell 706 and the adjacent connecting pipe 709. The first guide frame 703 located on the upper side is fixedly connected to two second guide frames 713 (to... Figure 10For example, in the figure, the three first sliding shells 706 on the left are slidably connected to second sliding shells 712 (this number is only for illustrative purposes, and the specific number can be adjusted according to the actual situation). The second guide frame 713 is provided with an inclined surface. The inclined surface of the second guide frame 713 is used to squeeze the adjacent second sliding shells 712. When the second sliding shell 712 is squeezed by the second guide frame 713, the adjacent spring of the second sliding shell 712 is in a compressed state. When several first sliding shells 706 slide into the spiral groove along the straight groove in the adjacent guide groove 705, the arrangement of several first sliding shells 706 is changed, so that several first sliding shells 706 change from a straight arrangement to a spiral arrangement. When several first sliding shells 706 change to a spiral arrangement, the second sliding shells 712 no longer contact the corresponding second guide frame 713. The second sliding shells 712 are popped out by the spring, so that the first sliding shells 706 near the second guide frame 713 no longer deliver sewage into the adjacent connecting pipe 709, thereby reducing the amount of sewage entering.

[0047] Working principle: In this embodiment, the existing MBR system is replaced by the components contained in the filter module 7. Before treating the sewage, the connecting pipe 709 needs to be connected to the existing pump. During the sewage treatment process, the existing pump draws the corresponding first sliding shell 706 through the connecting pipe 709, so that the sewage passes through the membrane fiber 708 and enters the upper first sliding shell 706 (when the sewage passes through the membrane fiber 708, solid impurities remain on the outside of the membrane fiber 708) and are discharged through the connecting pipe 709.

[0048] When all the swing plates 15 are arranged at an angle and cover the lower side of the first guide frame 8 (before this, the blocking member 10 no longer covers the lower side of the bearing frame 5, and at this time, the activated sludge on the upper side of the blocking member 10 is being cleaned), the control terminal controls the rope winding member 711. The rope winding member 711 no longer pulls the adjacent second connecting column 707. Under the action of the adjacent tension spring, several first sliding shells 706 gradually slide from the straight groove in the guide groove 705 into the spiral groove, thereby changing the arrangement state of several first sliding shells 706 and related parts, so that several first sliding shells 706 switch from a straight arrangement to a spiral arrangement. After several first sliding shells 706 are spirally arranged, the second sliding shell 712 no longer contacts the adjacent second guide frame 713. It is popped out by the spring adjacent to the second guide frame 713, so that the first sliding shell 706 near the second guide frame 713 no longer conveys sewage into the adjacent connecting pipe 709. While reducing the amount of sewage entering, it ensures the uninterrupted sewage treatment process.

[0049] After the activated sludge on the upper side of the shield 10 is cleaned, the control terminal controls the rope retractor 711, which pulls the adjacent second connecting column 707. Several first sliding shells 706 then gradually slide from the spiral groove in the guide groove 705 into the straight groove (during this process, the tension spring is gradually stretched). This changes the arrangement of the first sliding shells 706 and related parts, switching them from a spiral arrangement to a straight arrangement to restore the initial working state. Simultaneously, during the reset movement of the first sliding shells 706… In the middle, the second sliding shell 712 is squeezed by the inclined surface of the adjacent second guide frame 713 (the adjacent spring is in a compressed state at this time), thereby restoring the first sliding shell 706 near the second guide frame 713 to the state of conveying sewage into the adjacent connecting pipe 709 (the above action is only used to describe the single conversion state of all the first sliding shells 706. In order to increase the efficiency of self-cleaning, it can be repeated multiple times. In addition, the membrane fiber 708 comes into contact with the surrounding water during the movement of the corresponding first sliding shell 706, and the membrane fiber 708 achieves self-cleaning by rinsing).

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
